2/3(n + 9) = 12

What is N?

n = _

N + 9 = 12 means N is a number which, when added to 9, must give the answer 12. So N can only be the number 3 because only 3 + 9 is equal to 12.

9) (-12) – 3 5-15. 10) (-2) – 5. = -7. 11) (-9)–1 = -10. 12) 3-1. = 2. 13) 10- (-3) = 13 ... n-4 = 22. 9) the product of c and 10 is 24. 10) the sum of a number and 7 is 44 ... 17) (-5)-(-9) . ” (+8)+6-7. 18 (-26) – (-5) -7. 18) (-3). (-1). 24. 19) ī. ” (-2). 3 -2. -3.
